I've been thinking of a what if scenario using a couple of situations from the early part of Atlantis.
Anyway, it was discovered that the first time the Atlantis expedition discovered the city, they ran into some problems and they all died except Weir who unexpectedly travelled back in time to the time of the Ancients. Well what if, in this first time, the Ancients had initially designed a failsafe to begin with and left a small stockpile of ZPM's so that when the Atlantis team come in there now have some ZPM's, Puddle Jumpers, Drones, a time travelling Puddle Jumper, access to the whole city and information and the ability to travel back to Earth. Because of this no reason to travel to the Athosians planet and wake up the Wraith prematurely.
How would have events have turned out after this scenario other than two way travel between Earth and Atlantis allowing Ancient tech to be studied by both sides.
